'.lO` ALL 4WHOM IT MA'J(` OONCERN:

Be it known that I, THOMAS H. BOMAR, of Atlanta, iu the county of Fulton, and in the State of Georgia, have invented certain new and'iiseful Improvements -in/CanCouplings; and dojhereby declare that the following'is a full, clear, and exact description thereof, reference being vhad tothe accompanying drawings, and to the lettersof reference marked thereon. i

The nature of my invention consists in the construction and general arrangement of a car-coupling, which -is different from any other now in use, and which combines lightness and simplicity as well as strength, and is not liable to get out of order. And the advantages of the same are, that it is self-acting, so that cars canbe coupled from the engine without the supervision of a coupling-hand. It does away with the danger heretofore attending thecoupl'ing of cars. It saves time in themaking up of trains and shifting o f cars.- A brakesman on the top of the vcars can eut them loose at any time, in case of fire o' other accident, even while running. `It

can be used with common coupling, besides many others, which will be readily seen.

In order to enable others skilled in the art to make and use my invention, I will now proceed to ydescribe its-construction andloperation, referring' to the annexed. drawings, which form a part of this specification, and iu whichi v y Figure 1 is a side section, and

Figure 2 a rear view. Y

'G represents a leouplingbox, made in any of the known and usual ways, and provided-in the centre of its lower side with an inclined plane, A, which is slanting towards-,the mouth of the box. v

In therearof and close to said inclined plane 'is a wrought-iron pin, B', which passes through the bottom of the box, and firmly secured thereto. The top of said pin is bevelled, so as to form a continuation of the 'inclined plane.`

When the coupling-link H is inserted in tothe mouth of the coupling-box, it glides up along the inclined plane A and top of the pin B, falling down in rear thereof, thus coupling the cars. By this arrangement, the

weight o f the train'falls on 'a' solid support, unconnected with any kind of movable pin, hinge, ball, or bar, aud

as both the inclined plane and the wrought-iron pin, backing .the same up, are very strong, they cannot be broken; and since they are'permanent-ly-iixed, they cannot be lost.

In case of wear, the pin B can be readily replaced at small expense; thus the bumper will last several years longer than any heretofore invented. K

The top of the coupling-box is provided with a. slot, the front end of whiehis just above the pin B, and in this end annov'able arm, D, is pivoted, said arm falling'ldown and striking the rear side ofthe said pin B above the coupling-link. This arm serves to hold the link horizontal, the more readily to enter the next coupling,

Aandfnlso toprevent the'link'from being forced orthrown above the top of the inclined plane, and thus severing the train.

- In the rear part of the eoupling-box are stops, E E, which arefnecessary to make the link climb the inclined plane, and force back' the movable arm when inserted into the other coupling-box. Were it not for these stops the coupling-.link would push through.

In rear of the pin B, and between it and the stops E E, is an elevating-link, C, which consists of iron, or other suitable material, and passes fi-orn above the box in grooves on its sides and bottom. The upper ends of thislink are attached to chains, F, which are passed up to the platform of the cars, or to their top, and by this improvement, cars can be uncoupledi-not only when an engine is attached to pull out the links, but also when standing still on the track, for, by a few jerks of the chain, the elevating-link() throws the coupling-link above and on top of thejinclinedplane, thus cutting asund'er the train. v A

l The movable arm D is alsol connected tothe same chains,.F F., and the connection so arranged that the arm will be raised before any motion isimpart'ed to the elevatinglink. Y

By passing the' coupling-link H back through the open space above the'stops E E,.the coupling is so 'adjusted as not to couple, (end at the same time not to lose the linky) this adjustment to be used when it is desired to push back a.- few cars withouteonnecting them.

Having thus fully described, my invention, what I claim as new, and desire to secure by Letters Patent, is- The arrangement of the pvoted 'arm D, angular elevating-link C, stops E E, inclined plane A, and pin B in the drawi-head G, all constructed'and used substantially as specified.

In testimony that I claim the foregoing, I have hereunto setmy hand, this 1st day of June, 1868.
